Why is lanolin used to treat the medicine combs? I did get some, but would a good oil work also?
Use nothing on your horn comb to treat it but lanolin, preferably our unsulfonated lanolin, because it is from the same animal – a sister to the horn, you might say. Oil is not just oil, and it is not a matter of being ‘good’; the oil must be correct – and yes, it does matter. Lanolin somewhat waterproofs and seals the horn comb. Any other soaking will make the comb swell, thus ruining it. (Read our Horn Comb tutorial carefully!)
Never get your horn comb wet! Never keep it by your sink or in the bathroom!
